A 9-year-old boy presented to the emergency department of a paediatric hospital with non-painful lesions on his lips and inside his mouth, associated with lip swelling. On examination, his oral mucosa and lips showed numerous blisters with yellowish serofibrinous content and lip oedema. An eye examination revealed bilateral conjunctival injection. Genitalia was unaffected and no other skin lesions were found. He was on day 4 of clarithromycin prescribed for atypical pneumonia caused by Mycoplasma pneumoniae. The patient was diagnosed with M. pneumoniae-associated mucositis and was started on topical treatment with fusidic acid and betamethasone, with gradual improvement of the oral lesions.

China officially recognized atypical pneumonia outbreak in December 2019; on 11 March 2020, the World Health Organization declared COVID-19 as a pandemic that is produced by a new coronavirus, named SARS-CoV-2, of rapid transmissibility, which can be asymptomatic, with mild to severe respiratory symptoms, and with cardiovascular, neurological, gastrointestinal, and cutaneous complications. Considering that the pandemic prolonged more than initially expected was prognostic, it is essential for the medical community to identify the signs and symptoms of COVID-19. Thus, this work’s objectives were to present cases of cutaneous lesions observed in COVID-19 Mexican patients. We register cutaneous lesions in COVID-19 patients referred from internal medicine and otorhinolaryngology services to dermatology. We presented four interesting cases with cutaneous lesions, including exanthema morbilliform, urticaria, chilblains, ecchymosis, and facial edema, and review the available literature. The most frequent cutaneous markers are rash, chilblains, and urticaria. Skin lesions may be the first manifestation of COVID-19, accompany initial respiratory symptoms, or appear during the disease course. Symptoms associated with vascular changes (livedo reticularis and vasculitis) are considered of poor prognosis.

Purpose: Although acute conjunctivitis has been listed from the beginning as a possible sign of COVID-19, the likelihood of this association remains unclear. The aim of this study was to investigate the relationship between COVID-19 and conjunctivitis. Methods: In this retrospective, observational study, we recruited all patients with signs and symptoms of acute conjunctivitis seen at the Eye Emergency Department (ED), Turin Eye Hospital, between 01/01/2020 and 12/05/2020 and cross-checked our data with the Piedmont Region online COVID-19 registry in the same period. Results: Among 10,065 patients seen at our ED during the timespan considered, 88 underwent a nasopharyngeal swab (NS) for SARS-CoV-2 detection within 4 weeks before/after our examination. On average, NS was performed −0.72 ± 1.8 weeks before/after eye examination. Of the 77 patients with a negative NS, 26 (33.8%) had a diagnosis of acute conjunctivitis, whereas the remaining 51 (66.2%) had other eye disorders. Among the 11 patients with COVID-19, 7 (63,6%) had a diagnosis of acute conjunctivitis. We found a non-statistically significant increase in NS positivity rate (21.2%) among cases examined at our ED for acute conjunctivitis, compared to the NS positivity rate (7.3%) in patients examined for all other eye conditions ( p = 0.092). The Odds Ratio of having a positive NS in patients with acute conjunctivitis was 3.43 (95% I.C. = 0.9–12.8, p = 0.06). Considering online-registry data of Turin population during the same time-span, among 2441 positive NS cases only 27 (1.1%) presented with acute conjunctivitis. Conclusion: Our results do not reveal a statistically significant correlation between COVID-19 and acute conjunctivitis. Synopsis The present study analyzes retrospectively data from a tertiary eye referral center to investigate the relationship between COVID-19 infection and conjunctivitis.

Gliding Mechanism

ABSTRACT Mycoplasma pneumoniae is a major cause of bronchitis and atypical pneumonia in humans. This cell wall-less bacterium has a complex terminal organelle that functions in cytadherence and gliding motility. The gliding mechanism is unknown but is coordinated with terminal-organelle development during cell division. Disruption of M. pneumoniae open reading frame MPN311 results in loss of protein P41 and downstream gene product P24. P41 localizes to the base of the terminal organelle and is required to anchor the terminal organelle to the cell body, but during cell division, MPN311 insertion mutants also fail to properly regulate nascent terminal-organelle development spatially or gliding activity temporally. We measured gliding velocity and frequency and used fluorescent protein fusions and time-lapse imaging to assess the roles of P41 and P24 individually in terminal-organelle development and gliding function. P41 was necessary for normal gliding velocity and proper spatial positioning of new terminal organelles, while P24 was required for gliding frequency and new terminal-organelle formation at wild-type rates. However, P41 was essential for P24 function, and in the absence of P41, P24 exhibited a dynamic localization pattern. Finally, protein P28 requires P41 for stability, but analysis of a P28− mutant established that the MPN311 mutant phenotype was not a function of loss of P28.

In this case, a 43-year-old male presents to the emergency department complaining of blurred vision during the past few days. He appears apprehensive. His eye examination is completely normal. On the basis of his increased respiratory rate and apprehension, a diagnosis of anxiety state is made, and he is discharged home. He returns the next day with continuing symptoms. On this occasion, an arterial blood gas is ordered, which eventually reveals his correct diagnosis.

In Pregnancy

Pneumonia in pregnancy is associated with adverse maternal and foetal outcomes, and intensive treatment with appropriate antibiotics is essential. However, cases caused by pathogens that are resistant to antibiotics suitable for the developing foetus are challenging. We herein report a case of macrolide-refractory Mycoplasma pneumoniae pneumonia in pregnancy. A 40-year-old multigravida with twin pregnancy complained of cough and fever at 13 weeks of gestation and was diagnosed with pneumonia. Even though empiric treatment with ceftriaxone and oral azithromycin was started, her condition deteriorated rapidly. The findings of chest computed tomography suggested Mycoplasma pneumoniae pneumonia. Since azithromycin did not work, this strain was considered to be macrolide-refractory. Garenoxacin, an oral quinolone, was selected and was dramatically effective. The use of quinolone could be justified with the emergence of drug-resistant bacterial/atypical pneumonia and in the maternal life-threatening condition.
